No one was injured in the accident, which happened about 8:30 a.m., but Conway asked that motorists avoid the intersection at routes 5 and 92 and Lyndon Road -- one of Onondaga County's busiest intersections -- until the signals can be restored. All traffic lanes are affected, he said.

National Grid and state Department of Transportation crews are on the scene to fix the signals. DeWitt police meanwhile are directing traffic by hand, Conway said.

Conway said he did not know what type of truck ran into the cable or whether the driver would be ticketed.
